Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for storing and displaying handwritten information input from an electronic pen, and particularly a technique for identifying and displaying handwritten information input in various situations so that the user can easily use it. Regarding

[0002]

2. Description of the Related Art WO 00/73981 is a document disclosing a technique for inputting handwritten information from an electronic pen. This document shows a technique for generating electronic data while adhering ink to a paper surface and inputting the electronic data to an information processing device. When inputting information with an electronic pen, the input paper surface is made of carbon black that absorbs infrared light on the paper surface, and is represented by the combination of the size of the symbol mark and the combination of the deviation direction of the symbol mark from the raster line grid Use a printed position code. The electronic pen includes a diode that emits infrared light and a sensor that responds to the reflected light of the infrared light, and emits infrared light when the pen tip of the electronic pen touches the paper surface and the writing pressure sensor operates. The position code is calculated from the infrared light image of the reflected light to obtain the coordinates of the pen tip on the paper surface, and the movement locus data of the pen is generated and sent to the information processing device. The information processing apparatus displays the received pen movement trajectory data as it is.

[0003]

When pen movement locus data is input from the electronic pen using the above-mentioned conventional technique,
There are cases in which a plurality of pens are used for inputting on one sheet of paper, or even one pen is input with a time difference. For example, examples of input using a plurality of pens include application forms, approval forms, delivery slips, colored paper for miscellaneous writing, signature sheets, and entry on test answer sheets. In these cases, the pen used for input and the user of the pen are often different. Examples of the case where data is input with a time lag even with a single pen include class notes, a diary, manuscript paper, a schedule book, an address book, and a chart. In most of these examples, the capacity of the paper is sufficiently large compared to the amount of information input in one batch, and most of them are added to the empty area at a later date.

In the above-mentioned usage scene, when the input pen movement locus data is displayed / printed without any contrivance as in the prior art, the used pen and the additionally written portion are identified. Is difficult. If it becomes possible to easily distinguish by displaying the digitized data, it will be convenient in various respects. For example, in a delivery slip, if you can easily identify the information filled in with a pen used by each person in charge at the time of reception, shipping, and delivery on one slip, you can respond to the inquiry from the user who ordered. It makes it easier to track the whereabouts of deliveries.

An object of the present invention is to solve the above problems and provide an information processing apparatus and a display control program capable of identifying and displaying data input by a pen or the like used.

[0006]

SUMMARY OF THE INVENTION In the present invention, the movement locus data (identification display) is associated with the movement locus data of a pen received from an electronic pen for ink writing on a paper surface and writing.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing the system configuration of an embodiment of the present invention. The system is the information processing device 220.
And one or a plurality of electronic pens 201 and 202. The user of the electronic pen 201 and the user of the electronic pen 202 write information 211 and 212 on one sheet of paper 210, respectively. Each electronic pen transfers information 221 and 222 to the information processing device 220. Each piece of information includes paper identification information 230, electronic pen identification information 241, 242, and handwriting information 251, 252 composed of time-series position information processed as pen movement trajectory data. The paper identification information 230 may be input from the input device of the information processing device 220. When the paper information is sent from the electronic pen, data indicating that the predetermined position of the paper is checked by the electronic pen is sent to the information processing device 220, and the predetermined position of the paper and the type of the paper are associated on the information processing device side. It should be input by the method of managing by

Next, the paper (medium) used in the embodiment of the present invention
Will be described. The position code is printed on the paper with carbon black that absorbs infrared light. Carbon black looks light gray to human eyes and does not impair the aesthetics of paper. FIG. 14 shows a method of representing the position code by the direction of deviation of the symbol mark from the grid point of the raster line. Horizontal raster line 1
The points where 301 and the vertical raster line 1302 intersect are referred to as grid points 1303. With respect to this lattice point, the symbol marks are upper 1310, lower 1311, right 1312,
It is arranged on any of the left 1313, and any symbol mark is on the raster line. The amount of deviation from the grid point is constant in any direction, but it must be smaller than the raster line interval. Here, a, b, and
The values c and d are assigned.

FIG. 15 shows a paper (medium) used in this embodiment.
The following shows the layout relationship between the raster line and the symbol mark when the is cut out in a region of a certain size. The example area contains four raster lines each in the horizontal and vertical directions,
When the values of the symbol marks are read sequentially from the top in the row direction, a position code V of V = “acda, cbda, bcda, acda” is obtained. At this time, using a certain function G, [X, Y] = G (V) is converted into the center coordinates [X, Y] 1401 of this area. V = F (X, Y) is calculated with respect to the value of the coordinate [X, Y], and the symbol mark is laid out in advance on the entire paper surface according to the calculation result. The symbol mark is printed with carbon black as described above.
Raster lines do not need to be printed.

The electronic pen described below includes a diode that emits infrared light and a sensor that responds to the reflected light of infrared light. A pen ink pigment that transmits infrared light is used. When the pen pressure of this electronic pen touches the paper surface and the writing pressure sensor operates, infrared light is emitted and an image of reflected light is obtained. If only the symbol mark printed with carbon black absorbs infrared light on the paper surface, the electronic pen consequently obtains an infrared light image in which only the symbol mark portion is extracted. If the position code is calculated from this image and the coordinates are calculated, the coordinates of the pen tip on the paper surface can be known.

FIG. 16 shows a paper surface on which a preprinted position code, a preprinted portion, and a portion handwritten by an electronic pen are combined.

The synthetic paper surface 1500 is divided into a layer P1501 of a position code to be printed in advance, a layer Q1502 of a portion to be printed in advance, and a layer R1503 of a portion handwritten by an electronic pen. Only the layer P has a symbol mark that absorbs infrared light, and the layers Q and R transmit infrared light. When writing the portion of layer R on the paper surface on which the layers P and Q are printed in advance using the electronic pen of Prior Art 1, the electronic pen seems to have extracted the symbol mark that absorbs infrared light. An image of only the layer P is obtained. The image is a small area centered on the pen tip, not the entire page. This narrow area must be large enough to get the position code and coordinates. The electronic pen can obtain continuous data of the coordinates of the pen tip based on continuous images of the layer P. As a result, the reproduction of the continuous data of this coordinate is the handwritten portion of the layer R.
That is, the electronic pen of the related art 1 can obtain the electronic data of the layer R without being affected by the layer Q of the portion to be printed in advance. Furthermore, for layer Q, if electronic data for the coordinates on the paper surface are known, layer Q and layer R
It is also possible to obtain electronic data obtained by combining and. Thereby, for example, it is possible to partially cut out the continuous data “Suzuki” of the layer R described in the “name field” of the layer Q.

The information processing apparatus accepted at 13:15 of 1/23. (2) Using the pen U2 on the paper P1, the recipient's name and the date of receipt are entered in this order, and the information is transferred to the information processing apparatus. The information processing apparatus accepts at 14:00, 1/24. . (3) Using the pen U2 on the paper P1, the remarks are additionally filled, and the information is transferred to the information processing apparatus, and the information processing apparatus receives the information at 1/30 at 14:20.

FIG. 5 is a flow chart showing the processing for displaying the input data of the electronic pen by executing the pen input data processing program in the information processing apparatus.

The information processing apparatus 220 executing the pen input data processing program displays a command selection button group 601 as a menu of the processing program on the display screen 600 (501). When the management data is selected, the management data and the image data of the form form are combined and displayed on the display device 2. Unless otherwise specified, the handwriting information in the selected management data is displayed in the normal display mode in which all the handwriting information is displayed in the same treatment (color) (502). The display screen in this state is shown in FIG.

When "pen identification display" is selected in this state (503), the pen identification information of each handwriting information in the management data and the display color management table are referred to, and each pen identification information is displayed in a different color. (504). As shown in FIG. 4D, the display color management table is a table that stores the correspondence between pen identification information and display colors, and is stored in the hard disk 10 of the information processing device 220. A display screen of the processing result of step 504 is shown in FIG. Electronic pen identification information 30
Data in which 1 is U1 ([X1, Y1] to [X
6, Y6]) is displayed in the first color (black) (60
2) Regarding the data ([X7, Y7] to [X9, Y9]) in which the identification information 301 of the electronic pen is U2,
It is displayed in the second color (red) (603). "Suzuki" entered using the pen of U1 "03-3333-5
"555""1966""2""3""TOKYO""2
"002""1""23" [A2] is displayed in black and U
"MF""1""24" input using the pen of 2
(Strikethrough) "F2" is displayed in red. In this way, for example, if the pen group used by the applicant is designated to be displayed in black, and the pen group used by the receptionist is designated to be displayed in red, It is useful to distinguish at a glance what is filled in by the person in charge and the portion filled in by the person in charge of reception on the application side. If the color of the ink actually attached to the paper by the electronic pen and the color displayed on the information processing device are made to correspond to the same or similar color in the display color management table, the document handwritten on the actual paper surface and the electronic The display colors of the electronic data stored in can be matched. In addition, you can dare to associate a specific electronic pen with a display color different from the actual ink, which allows you to identify the input data when you have to use the same color ink on paper. Can also be

When the mouse cursor 604 is moved to the data display portion in the display state of FIG. 6, the identification information of the electronic pen used at the time of input may be displayed in the small window 605. In this example, the pen identification information value “U1” is displayed on the data display portion of the applicant birth date field. The attribute display of the pen used at the time of such input is useful when the owner and the use place of each pen are known. The menu button is displayed in a different color from other menu buttons so that it can be identified that the pen identification display is selected.

Next, when "Display for each pen" is selected (5
05), only the handwriting information input by the same pen in the management data is extracted and displayed. Unless otherwise specified, the pen in which the handwriting information is first input in the management data is selected and displayed. A pen selection button 606 is also displayed on the display screen 600 so that the pen used in the management data can be selected (506). In response to the operation of this button by the user, the pen identification information is switched so that the handwriting information input by the selected pen is displayed (507).
In this example, since two types of pen identification data U1 and U2 exist in the management data, two switch buttons 606 are displayed. If there is more pen identification data in the management data, a switch button corresponding to that number is displayed. Alternatively, only one switching button may be displayed, and the pen identification code may be sequentially switched by rotation manner. FIG. 8A shows a state in which the pen U1 is selected when displaying the management data of FIG. Electronic pen identification information 30
Data in which 1 is U1 ([X1, Y1] to [X
6, Y6]) is displayed. FIG. 8B shows a state in which the pen U2 is selected for displaying the management data of FIG.
In this case, data ([X7, Y7] to [X9, Y9]) in which the identification information 301 of the electronic pen is U2 is displayed. A “pen color display button” may be displayed on the display screen at this time, and the display color management table may be referred to when displaying each to display the color specified in the display color management table. FIG. 8B shows an example in which the display color of the pen U2 is red by pressing this pen color display button.
Such a pen-by-pen display function is useful when it is desired to confirm the information input by one pen. In each case, the display color of the menu button indicating the selected pen is changed and displayed.

When "Reception date identification display" is selected (50
8), referring to the reception date / time information and the reception date / color management table of the handwriting information in the management data, the first reception date (1/23)
The data ([X1, Y1] to [X6, Y
6]) is displayed in the first color (purple) and the data ([X7, Y7]-
[X8, Y8]) is displayed in the second color (yellow) and the data ([X8, Y8]) input on the third reception day (1/30) is displayed.
9, Y9]) is displayed in the third color (green)
(509). The display screen at this time is shown in FIG. Here, "Suzuki""03-3333-5555""19"
66 "" 2 "" 3 "" TOKYO "" 2002 "" 1 "
"23" [A2] is displayed in purple, "MF""1"
"24" is displayed in yellow and (strikethrough) "F2" is displayed in green. Such a display that identifies the reception timing is useful for identifying at a glance which item was entered at the same timing or which item was entered at a different timing from other items. is there.
Here, the color is changed according to the date, but the color may be further finely classified and displayed in units of hours and minutes. Also,
It may be possible to use it together with the pen identification display. At this time, the reception date and time information may be displayed in the small window 406 in response to the mouse cursor 405 moving onto the data display portion. In FIG. 9, on the corrected data display portion of the remarks column, the value of the reception timing is “1/30, 14:
20 "is displayed. Such a display of the reception timing is useful when it is known which item has been input and when (to be precise, the information processing apparatus side knows the reception timing). The reception date-color management table stores the correspondence between the reception date and the display color in the management data, as shown in FIG. 4 (e). It is stored in the hard disk 10 of the information processing device 220.

When "Display by reception date" is selected (51
0), data is extracted for each reception date of the management data, and handwriting information is displayed for each reception date (511). Unless otherwise specified, the data of the first date is displayed and the reception date switching button 607 is also displayed on the same screen. The handwriting information to be displayed is sequentially switched in response to the reception date switching button 607 being pressed.
In this example, 1/23 → 1/24 → 1/30 → is repeated (512). When an operation is requested to display the input part at the third reception timing (for example, 1/30), the information display screen follows the data in Table 3 and the data 301 of the reception date and time 305 is 1/30. ([X
9, Y9]]) only. Such a display for each reception timing is useful when it is desired to confirm the input information at one reception timing. When "Display by attribute" is selected (513), the attribute information 3 of the management data
A value is displayed for each attribute based on 06 (514). If there is such a display by attribute, even if the paper used for filling is laid out in a complicated manner, it will be in a neat format,
It is useful to know the input value of each item. For example, when a large number of management data input in the same form are stored, by displaying only specific items, it becomes easy to compare the input data of each item. FIG. 11 shows the display state at this time. At this time, when the mouse cursor 531 moves to the display portion of the data, all attribute information regarding the data is displayed in the small window 532. In this example, the pen identification information value “U1” and the reception date / time information value “1/23, 13:15” are displayed on the data display portion of the applicant name field.
Is displayed. If the information processing apparatus is also associated with other attribute values related thereto, these may be displayed together.

The attribute-based display and the reception date / time information may be interlocked with each other to display the attribute-based display in the order of reception. FIG. 12 shows the display state at this time. Based on the attribute information 306 and the reception date / time information 303, values are displayed for each attribute in the order of reception timing. If the reception timing has the same value, the data management order or the default priority order is used. The order of stroke data of the electronic pen is reflected in the data management. Explaining with an example of the figure, "Suzuki""03-3333-555"
5 "" 1966 "" 2 "" 3 "" TOKYO "" 200
Since the data is managed in the order of "2", "1", "23" [A2], the data is sorted and displayed for each attribute according to the data. Such a display of the reception timing order for each attribute is useful for knowing which item was entered in which order. Especially, it is effective when knowing the entry order for the same item. In this example, the remarks column is filled in at two timings, but its history can be easily confirmed.

FIG. 13 shows a state in which handwriting information is sequentially reproduced at a predetermined time interval in the order of reception timing by attribute.
Values are additionally displayed for each attribute in the order of reception timing based on the attribute information 306 and the reception date / time information 303. In the example of the figure, first, the value "Suzuki" (display 522) in the applicant name field is displayed, and then the value "03" in the applicant telephone field.
"-3333-5555" (display 524) is additionally displayed. Such reproduction display for each attribute is useful for intuitively following the order of input rather than following the order in batch display. Such a process may be provided as a processing program, and the related information for each data is sequentially displayed in the order in which they are input, which is useful for capturing the data with the sense of input by the writer.

The embodiment of the invention has been described on the assumption that there are three reception timings with one electronic form U1 and two electronic pens U1 and U2.

As an example in which the information display method of the present invention is useful, a request for approval, a delivery slip, a colored paper for message writing, a signature paper,
Examples include exam answer sheets, class notes, diaries, manuscript sheets, schedule books, address books, and medical chart entries. The draft approval draft is prepared by the creator, and the readers and decision makers on the way fill in the comments with their electronic pens as necessary. Mailing is often used for this circulation, and there is a time lag in input. In the delivery slip, the destination part of the slip is filled by the sender with his / her own electronic pen or the electronic pen provided at the delivery reception desk. Fill in what you need to fill out. After that, the consignee on the way fills in if necessary, and finally the delivery destination is asked to write to the resident of the delivery destination by the delivery destination's electronic pen or the delivery person's electronic pen. Since this delivery slip is mailed in the form of being attached to the package, there is a time lag in input.
For example, all students in the class fill in the colored paper for writing in order with the same electronic pen. However, it is rare for all students to get colored paper all around at once, and in many cases the remaining students will get colored paper later. The signature form is filled in by a person who accepts the signature using an electronic pen owned by an exerciser requesting the signature. During the exam, the answer sheet for the exam is filled in by the student who is solving the problem with his / her own electronic pen, then the teacher collects the answer sheet, and the teacher's electronic pen marks the answer sheets for all students in charge. To do. Generally, red is used as the ink for the teacher's electronic pen. Since the teacher will score in the staff room after collection, there will be a time lag in input. Basically, only oneself writes notes in the lesson with his / her own electronic pen, but there is a time lag in input because lessons occur every hour and every day. Also,
In general, class notes are divided for each subject. Every day, only myself fill in the diary with my electronic pen. The manuscript sheet will be filled out by the writer with his / her electronic pen, but there are cases where he / she deletes or corrects a part that he / she does not like. The schedule book, when the schedule is entered,
Fill in with your own electronic pen. The date does not match the date in the schedule book, and the input order is changed. In the address book, when the address is known, the user can fill in the address with his / her own electronic pen, or give the person in charge of the address to his / her own electronic pen to have the address entered. As for the medical chart, clerical staff, doctors, nurses, pharmacists, etc. fill in their own areas of responsibility. One medical record is assigned to one patient, and is added to the medical record each time this patient visits the hospital. If there is no margin on one chart, a new chart sheet will be added.
